Audio and text processing
This feature processes conversation audio for transcription and translation. If another person is involved, please obtain their consent before using it. When history saving is enabled, transcripts, translations, and summaries may be saved to your account.
Security practices
- App and API traffic is encrypted with HTTPS/TLS.
- Firebase Authentication protects account-based API calls.
- Backend processing, job state, and stored audio use Google Cloud services where needed.
- Stripe handles payment processing; LingoFlow does not directly store card numbers.
- Error logs are designed to avoid storing audio, transcripts, translations, summaries, and credentials.
AI training non-use
We do not use your audio, transcripts, translations, or summaries to train LingoFlow-owned AI models.
When external AI services are used, data is processed according to each provider's data protection terms. For OpenAI API-based processing, OpenAI states that API data is not used to train or improve OpenAI models unless the customer explicitly opts in.
